Could be. But most people forget that air drag and resulting heating of the tip is proportional to the air density. Elevations with elk and antelope have much lower air density than south Louisiana which is very close to sea level. The aerodynamic forces on the bullet at 2950 at sea level can be greater than at 3230 at 5000 ft. Twist rate and tip off angle come into play also, since failure occurs before much damping of the pitch and yaw.

This same lot of bullets never created a problem for us on the great plains or mountains at temps in the 80s, but started to cause trouble in Louisiana at temps in the 90s.

There's no doubt that these bullets work fine in a lot of different barrels, or Hornady would be so flooded with complaints they would have fixed the problem. Figuring out why these bullets fail in conditions where failure is common is the more challenging task.

Most of my hot shooting is done around 2600' elevation. Shooting elk and other animals is usually much cooler and higher elevation.

My barrel is a 8 twist Bartlein 5R Sendero contour. A lot of times I run 3-5 rounds in under a minute through my gun when I'm shooting long distance. I know F-class involves more rounds but my barrel will get pretty hot fast too.

6 groove. The humidity was high, but this barrel doesn't foul much. Only 700 rounds down the tube so the throat is still in pretty good shape. H1000 is a pretty clean powder. This is one of the smoother bores we've owned. Very quick clean up compared with most other barrels.

If you have any left from that lot send em to Hornaday with a description. Don't complain just describe.

They will do the right thing.

IMHO: If you take an attitude of trying to help the will be very very nice but if you complain or focus on how you were wronged or harmed the will treat you like you are trying to harm them or retaliate.

The matter has been forwarded to Hornady Engineering in a professional and friendly manner. We intend to cooperate with any ensuing requests for additional information or materials, but there have not been any yet.
